Climate control

[Jedster]

I own a VZ Crewman ssz with climate control. Everytime I put the foot down going up a hill or towing a heavy load or something it seems to shut the air con off. What the h is this, why does it do it and how can i stop it from doing it. Its annoying as s##t as I live in a hot part of the country. And just cos I'm going up a hill doesn't mean I want to get hot. Everything else seams to be ok. Water temp Oil pressure ect. Please help.

thanks

Its a vacuum problem mate, do a search and you will find plenty of threads on it. I replied to one yesterday in the VY section
